The Royal Guard is very hated, at least by the citizens of Snowdin.The areas have a much more industrial and dystopian theme.Monsters sealed themselves away to protect themselves from humans.

The war between humans and monsters happened in the 20th century, more specifically the Cold War era, as shown by the use of military outfits and tanks in the opening sequence.

Most of the swaps are the same as in Underswap, although Gaster (who instead is genderbent, together with his followers) and Riverperson, Onionsan and the Bird That Carries You Over A Disproportionately Small Gap and Shyren and Aaron do not swap with each other. While Undertale is a world where LGBT is fully accepted, Fellswap Gold is one where LGBT monsters are afraid to hold their handsпјЊoppressing their true willingsпјЊeven getting into jail just for telling their ideas, as the author lives in a similair situation. Rather than 'Kill or be Killed', monsters live under the rule of 'Oppress or be Oppressed'. It is set in the Cold-War era of the 20th century, and its setting is inspired by the totalitarian countries from that time, most notably the Soviet Union, as well as the book 1984 by George Orwell.
